Western Australia has recorded 194 new local cases of COVID-19 as parliament faces its first virus scare.
The new cases represent the state's highest daily tally yet and are in addition to eight travel-related cases, making a total of 202 new cases.
The figures include 18 self-reported positive rapid antigen tests.
A WA government spokesman has confirmed Labor MP Terry Healy is a close contact of a COVID-19 case.
Mr Healy, who sat in parliament for three days this week, confirmed in a message to the ABC that he had undergone a PCR test on Friday morning after finding out he was a close contact.
If Mr Healy's test comes back positive, other MPs who came into close contact with him could also be forced into seven days of isolation.
All MPs have been wearing masks in the legislative assembly, except when delivering speeches.
The assembly has social distancing measures in place, and it can only hold half of its 59 members in the chamber at one time.
Parliament House has also closed the public gallery and there is reduced capacity in the dining area to allow for social distancing.
MPs have also started a trial of video speeches and calls into the chamber for question time.
Further trials are expected to be conducted to potentially allow members to appear from home if forced to isolate due to COVID-19.
A total of 9,305 people were tested at state and private clinics yesterday.
No one is currently in hospital with the virus.
The state's booster vaccination rates stands at 55.3 per cent of the population over 16, while 98.7 per cent of those aged over 12 have received at least one dose, and 95.3 per cent have received two doses.
Vaccine mandate decision 'reeks of arrogance': Opposition
It comes as the WA Opposition continued to push for an answer on the state's border, saying some of the government's vaccine mandates were "inconsistent" and "vindictive".
Shadow Health Minister Libby Mettam said the majority of the eligible population had now received at least one dose of a vaccine and raised concerns about the onus that was being placed on small businesses to police mandates.
"It is vindictive of the McGowan government to be imposing rules on small businesses, which they are not imposing on themselves," she said.
"Those at Dumas House, in the Premier's own palace, are not having to be burdened with the same requirements.
"It does reek of arrogance."
Ms Mettam said many of the rules were not consistent with federal health advice.
"What we're seeing is a Premier who is drunk on power, who has delivered some of the most harsh sets of restrictions across this state, which are now clearly inconsistent," she said.
Nurses watching NSW industrial action
Meanwhile, after nurses and midwives went on strike this week in New South Wales to protest pay and working conditions during the pandemic, WA's nursing union said it had received numerous emails from members asking what its position was.
Australian Nursing Federation WA state secretary Mark Olson said while many frustrations were shared, "we're not going to be taking any industrial action presently".
Mr Olson said future moves would depend on the state government's response to issues like staff shortages and workloads.
"The government's got plenty of time to start moving in these areas," he said.
"I don't want to get to a stage where we've got nurses and midwives walking off the job in the middle of a pandemic."
Mr Olson said any industrial action would be up to the union's members and would depend on where the Omicron surge goes.
"If we can't get some guarantees about nurses not being thrown under the bus, then I think it's pretty obvious what the nurses will do," he said.
